IMPROVEMENT lN CONDENSERS FOR O|l.STlLLS.

Specifica-tion forming part of Letters Patent No. 117,873, dated August 8, 1871.

To vall 'whom it m ay concern:

Be it known that we, HIRAM XV. FAUCETT, of Titusville, Crawford county, and THOMSON Mo- GOWAN, of Meredith, Venango county, State of Pennsylvania, have invented an Improved Apparatus for Gondensing the Tapors of Distillation, of which the following is a full and complete description, reference being had to the accompanying drawing, of which- Figure lis a general perspective view with part of the water-box removed so as to allow a view of the vapor-cylinder. Fig. 2 is a longitudinal section of the vapor-cylinder with its connections.

The object of our invention is the rapid condensation of distilled vapors in a simple and effective manner.

For this purpose we have the water-box B, with the pan l) forming a continuation of its upper part, resting upon the edge of the still S and iilled with water from the pump or otherwise by the feed-pipe F. In the lower part of the water-box B, as shown, is placed the vapor-cylinder C, having a tail-pipe, T, with stop-cock.

' NVithin the vapor-cylinder C is the water-cylinder It, which is kept lled with water under pressure fromV the feed-pipe W, and, being perforated all over its surface with iine holes, throws the water infine jets in every direction throughout the interior of the vapor-cylinder O, this water-cylinder R resting on the collars ff, separates and frees from the vapor-cylinder C, so as to be readily removed for cleaning or repairs. The vapor, being brought from the top of the still S by the vapor-pipes V V through the water in the pan B and thewaterboX B, is carried down by the pipes V V, as shown, in the vapor-cylinder C, where it meets with the fine sprays of water, before mentioned, from the surface of the watercylinder R, the condensed vapor and water being drawn off together by the tail-pipe T, as shown.

It will be observed that the vapor-pipes V V are permanently covered with owin g cold water, almost from themoment of leaving the' still, and,

therefore, that the condensation begins sooner than in the ordinary present arrangement; that the water in the cylinder lt is under pressure from the head in feed-pipe W; and that the vacuum generated in the vapor-cylinder C, by the rapidity of this method of condensation, has a tendency to forward and assist the generalprocess.

To provide against the rupture or deran gement of the vapor-pipes V V, by the expansion and contraction ofthe metal water-box B and pan P in heating and cooling, they are provided with expansion joints in the perpendicular arms immediately joining the still.

The vapor-cylinder is set with a slight descent toward the tail-pipe T to facilitate its discharge.

We do not claim the use of vapor-pipes surrounded by cold water; neither do we claim, broadly, condensing vapors of petroleum by injecting' into them water or cold liquid in the form of a spray or shower in the condenser, as such has been patented by E. G. Kelley and A. H. Tait, June 18,1861, and reissued May 9,1871; neither do we claim a condenser having zigzag condensing-pipes parallel in sections, each section opening in and connected to a transverse supplypipe at the top and a transverse discharge-pipe at the bottom; nor do we claiin a cold-water feedpipe for casting jets of water on the outside of sectional condensing-pipes; but,

Havin g described our invention, what we claim as new, and desire to protect by Letters Patent, 1s-- The longitudinal cylindrical perforated pipe R, arranged within the condensing-cylinder C and communicating with the feed-pipe XV, as described, in combination with the vapor-pipes V V, surrounded by water in the water-box B and operating in reference to the still S, substantially as and for the purpose set forth.
